Advance of research on endoplasmic reticulum stress and genetic epilepsy / 中华医学遗传学杂志

Epilepsies are a group of chronic neurological disorders characterized by spontaneous recurrent seizures caused by abnormal synchronous firing of neurons and transient brain dysfunction. The underlying mechanisms are complex and not yet fully understood. Endoplasmic reticulum (ER) stress, as a condition of excessive accumulation of unfolded and/or misfolded proteins in the ER lumen, has been considered as a pathophysiological mechanism of epilepsy in recent years. ER stress can enhance the protein processing capacity of the ER to restore protein homeostasis through unfolded protein response, which may inhibit protein translation and promote misfolded protein degradation through the ubiquitin-proteasome system. However, persistent ER stress can also cause neuronal apoptosis and loss, which may aggravate the brain damage and epilepsy. This review has summarized the role of ER stress in the pathogenesis of genetic epilepsy.

A family study of congenital nephrogenic diabetes insipidus combined with hyperuricemia / 中华内分泌代谢杂志

Objective:To investigate the clinical and genetic characteristics, pathogenesis and treatment strategy of congenital nephrogenic diabetes insipidus(CNDI)combined with hyperuricemia.Methods:The clinical manifestations and laboratory data of an infant patient diagnosed as CNDI with hyperuricemia and his family members were collected and retrospectively analyzed. Whole exome sequencing(WES)was applied to detect the proband′s genome variation of each exon and suspected variants of AVPR2 and ABCG2 were verified by PCR-Sanger sequencing of members from his pedigree. Furthermore, we retrospectively collected the serum uric acid levels of patients(≤14-year-old) with CNDI in the First Affiliated Hospital of Zhengzhou University from January 2015 to January 2022.Results:The proband was clinically diagnosed with CNDI and the rest of the family members had no symptoms of polydipsia or polyuria. In addition to the proband, his father was also suffered from hyperuricemia. WES showed that the proband carried a hemizygous AVPR2 gene variation(p.S331R)and a heterozygous ABCG2 gene variation(p.N308K). The former was X-linked recessive inheritance from his mother, and the latter was autosomal dominant inheritance from the father. Fraction excretion of uric acid(FEUA)of the proband and his father with hyperuricemia were 3.1% and 2.7%, respectively. Twelve children(≤14-year-old)were diagnosed with CNDI from the respective study. Among all the cases, 11 patients were male and 1 was female, ranging from 3-month to 14-year-old. Five patients were accompanied with hyperuricemia.Conclusion:Children with CNDI may be complicated with hyperuricemia, and the regimen of hydrochlorothiazide combined with benzbromarone is effective. The pathogenicity of the AVPR2 gene variation(p.S331R)and ABCG2 gene variation(p.N308K)in this pedigree needs to be further studied.

The short-term and long-term prognostic analysis in patients with chronic total occlusion acute non-ST segment elevation myocardial infarction / 中华内科杂志

Objectives:To investigate the clinical impacts of chronic total occlusion (CTO) in acute non-ST segment elevation myocardial infarction (NSTEMI) patients underwent primary percutaneous coronary intervention (PCI).Methods:A total of 2 271 acute NSTEMI patients underwent primary PCI from China Acute Myocardial Infarction Registry were enrolled in this study and divided into the CTO group and the non-CTO group according to the angiography. The primary endpoint was in-hospital mortality and mortality during a 2-year follow-up. The secondary endpoint was major adverse cardiovascular events (MACE) including revascularization, death, re-myocardial infarction, heart failure readmission, stroke and major bleeding.Results:Thirteen-point four percent of the total acute NSTEMI patients had concurrent CTO. In-hospital mortality (3.6% vs. 1.4%, P<0.01) and 2-year mortality (9.0% vs. 5.1%, P<0.01) were significantly higher in the CTO group than those in the non-CTO group, respectively. Multiple regression analyses showed that chronic obstructive pulmonary disease ( HR 7.28, 95% CI 1.50-35.35, P=0.01) was an independent risk factor of in-hospital mortality, and advanced age ( HR 1.04, 95% CI 1.01-1.07, P<0.01), and low levels of ejection fraction ( HR 0.95, 95% CI 0.93-0.98, P<0.01) were independent risk factors of 2-year mortality. CTO ( HR1.67, 95% CI 1.10-2.54, P=0.02) was an independent risk factor of revascularization, but not a risk factor of mortality. Conclusions:Although acute NSTEMI patients concurrent with CTO had higher mortality, CTO was only an independent risk factor of revascularization, but not of mortality. Advanced age and low levels of ejection fraction were independent risk factors of long-term death among acute NSTEMI patients.

Research progress on tumor hyperthermia / 中华放射肿瘤学杂志

In recent years, increasing evidence has shown that hyperthermia is safe, effective and causes low toxicity. Hyperthermia can exert synergistic effect with other treatments, such as radiotherapy and chemotherapy. It has become an important adjuvant anti-tumor treatment secondary to surgery, chemotherapy, radiotherapy and biological treatment. Hyperthermia can improve the efficacy of radiotherapy and chemotherapy by directly inhibiting tumor cells and heat-induced radiosensitizing effect. Hence, hyperthermia is gradually applied in the multimodality treatment of tumors. In this article, we intend to review the research progress on the application of tumor hyperthermia in conventional radiotherapy, chemotherapy, immunotherapy and new biomaterials.

Association of sex hormones and bone turnover markers among men in the Northeast region of Henan Province / 中华内分泌代谢杂志

Objective:To examine associations of sex hormone levels with bone turnover markers(BTMs) among men in the Northeast region of Henan Province.Methods:From December 2015 to March 2016, 707 male subjects were selected from a National Epidemiological Survey-2014(Thyroid Disorders, Iodine status and Diabetes, TIDE)research—Henan sub-center survey by using multistage stratified cluster random sampling. Fasting venous blood was collected to determine the levels of luteinizing hormone(LH), follicle stimulating hormone(FSH), estradiol(E 2), testosterone(T), dehydroepiandrosterone-sulfate (DHEAS), androstenedione(AD), sex hormone binding globulin(SHBG), dihydrotestosterone(DHT), free testosterone(FT), osteocalcin(OC), pro-collagen type 1 N-terminal propeptide(PINP), C-terminal-cross-linking telopeptide of type 1 collagen(β-CTX), 25-hydroxyvitamin D [25(OH)D], and parathyroid hormone(PTH). Results:A total of 697 men with an average age of(46.6±15.9)years were included in the study. Pearson correlation analysis showed that age was positively associated with LH, FSH, T, and SHBG, while negatively associated with E 2, DHEAS, AD, FT, β-CTX, OC, and PINP, without significant correlation with DHT, 25(OH)D, and PTH. Pearson correlation analysis and linear regression analysis showed that E 2 was negatively associated with β-CTX; T was positively associated with OC, FSH was negatively associated with OC; LH, FSH, and SHBG were negatively associated with PINP; E 2, T, FT, DHT, and AD were positively associated with PINP. After adjusting for age and BMI, linear regression analysis showed that T was still significantly positively associated with OC and PINP, with 0.302 ng/ml and 0.015 ng/ml increasing for OC and PINP every 1 ng/ml increase in T; E 2 and DHT were positively associated with PINP, with 0.250 and 0.047 ng/ml increasing for PINP every 1 pg/ml increase in E 2 and DHT. Conclusions:Age is an important factor influencing sex hormones and BTMs. Serum levels of T, E 2, and DHT are associated with bone formation and bone absorption markers.

Objective To investigate the prevalence of nutritional risk (NRS2002) and malnutrition inhospitalized stroke patient and their nutritional intervention. Methods The stroke patients admitted to three de-partments of vascular neurology ward including cerebral hemorrhage, cerebral infarction and subarachnoid hemor-rhage in Beijing Tiantan Hospital from January 2018 to January 2019 were recruited using cluster sampling. Nutri-tional risk screening 2002 ( NRS 2002) was used to screen the nutritional risk of inpatients Malnutrition was as-sessed by criteria:(1) body mass index (BMI) <18. 5 kg/m2 with poorer general condition from January 2018 to January 2019;(2) Global leadership initiative on malnutrition ( GLIM) criteria were used except whole body muscle mass measurement from October 2018 to January 2019. The nutritional intervention for patients were closely observed during hospitalization. Results A total of 1532 patients were registered and1036 patients were included in the final analysis considering the inclusion and exclusion criteria. The prevalence of nutritional risk was 33. 0％ ( 342/1036) . The prevalence of malnutrition based on BMI and GLIM criteria was 0. 9％( 9/1036) and 2. 5％ (10/393) respectively. Among the 342 patients with nutritional risk, 112 patients received nutritional support therapy by tube feeding, but only 29 patients received nutritional support that met guideline standards. 81 patients received not standard nutritional support, and 2 patients received highly unregulated nutritional sup-port. No patients received sugar and electrolyte infusion, oral nutritional supplements ( ONS) , oral nutritional a-gents and compound nutrition intervention. The other 230 patients took hospital diet. Conclusion The prevalence of nutritional risk in hospitalized patients with cerebral hemorrhage, cerebral infarction or subarachnoid hemorrhage was high, and the prevalence of malnutrition was extremely low. There was a low proportion of nutri-tional support. High quality of large sample cohort studies will be conducted to show whether reasonable applica-tion of nutritional support therapy in patients with nutritional risk can improve patient outcome.

Microwave Hyperthermia Combined with Gemcitabine Inhibits Proliferation and Induces Apoptosis of Human Lung Squamous Carcinoma Cells / 中国肺癌杂志

BACKGROUND@#Lung cancer is one of the highest morbidity and mortality in the world and it is very important to find an effective anti-tumor method. Microwave hyperthermia, a new treatment technology, has been getting more and more attention. This study was designed to investigate the effects of microwave hyperthermia combined with gemcitabine on the proliferation and apoptosis of human lung squamous cell carcinoma (NCI-H1703 and NCI-H2170) in vitro.@*METHODS@#The proliferation of cells treated with microwave hyperthermia, the effect of gemcitabine on cell proliferation and the proliferation of cells treated with different methods of microwave hyperthermia and gemcitabine were detected by CCK-8 assay. Colony formation assay was used to measure the colony formation of human lung squamous cell carcinoma cells. Flow cytometry assay was used to detect the total apoptosis rates of the treated cells. Caspase-3, Caspase-8 activity assay was used to detect the activity of Caspase-3, Caspase-8 enzyme in each group of cells. CCK-8 assay was used to detect the effect of control group, AC-DEVD (Caspase-3 inhibitor) group, thermalization combined group, and thermal AC-DEVD combined group on cell proliferation. The levels of p53, Caspase-3, Cleaved-Caspase-3, PARP, Bax and BCL-2 protein expression were detected using Western blot assay.@*RESULTS@#Our results demonstrated that microwave hyperthermia inhibited the proliferation of lung squamous cell carcinoma. The IC₅₀ values of gemcitabine for the two cells were 8.89 μmol/L and 44.18 μmol/L, respectively. The first chemotherapy after microwave hyperthermia has synergistic effect on the two lung squamous cell carcinoma cells and can significantly inhibit the cell clone formation (P0.05). Furthermore, Western blot analysis showed that microwave hyperthermia combined with gemcitabine could up-regulate the p53, Caspase-3, Cleaved-Caspase-3, Cleaved-PARP and Bax protein expression.@*CONCLUSIONS@#Microwave hyperthermia combined with gemcitabine remarkably inhibit the proliferation and induce apoptosis of human lung squamous cell carcinoma in vitro. This effect may be associated with the activation of p53, cleavage of PARP protein, and induced the Caspase-3 dependent apoptosis.

Influencing factors on clinical response to conbercept for diabetic macular edema / 中华眼底病杂志

Objective To analyze the influencing factors on clinical response to conbercept for diabetic maeular edema (DME).Methods A total of 51 patients (51 eyes) with DME who underwent intravitreal injection of conbercept were included in this retrospective study.The general information (age,sex,body mass index,smoking history,drinking history),blood glucose indicators (duration of diabetes,fasting blood glucose,HbA 1 c),blood pressure indicators (history of hypertension,systolic blood pressure,diastolic blood pressure),lipid indicators [total cholesterol (TC),high-density lipoprotein (HDL),apolipoprotein A (APOA)],biochemical indicators [neutrophil concentration,hemoglobin (HB),serum creatinine (Scr)] were collected.The best corrected visual acuity (BCVA) and macular central macular thickness (CMT) before and after treatment were comparatively analyzed.CMT reduced not less than 20％ and BCVA increased by 2 lines as effective standards.Univariate analysis and multivariate logistic regression analysis were used to determine the factors affecting the efficacy ofintravitreal injection ofconbercept in patients with DME.Results Univariate analysis showed that diastolic blood pressure,HDL,serum neutrophil concentration,baseline CMT and baseline BCVA were associated with edema regression (P＜ 0.05);HbA 1 c was associated with vision improvement (P＜ 0.05).Multivariate logistic regression analysis showed that there was a history of smoking (OR=0.122,95％ CI 0.017-0.887),low diastolic blood pressure (OR=0.850,95％CI 0.748-0.966),low HDL (OR=0.007,95％CI 0.000 1-0.440),thin baseline CMT (OR=0.986,95％CI 0.977-0.995) were independent risk factors for failure outcome of edema regression (P＜0.05);long duration of diabetes (OR=1.191,95％CI 1.011-1.404),high APOA (OR=l.007,95％ CI 1.000-1.013) were independent risk factors for failure outcome of vision improvement.Age,fasting blood glucose,systolic blood pressure,TC,HB,Scr and other indicators had no effect on the efficacy of edema regression and vision improvement after treatment (P＞ 0.05).Conclusions Smoking history,long duration of diabetes,low diastolic blood pressure,low HDL level,high APOA level and thin baseline CMT are independent risk factors for the treatment of DME with intravitreal injection of conbercept.

Association of FOXO1 gene single nucleotide polymorphisms with type 2 diabetic nephropathy / 中华内分泌代谢杂志

Objective To investigate the association between single nucleotide polymorphisms ( SNPs) of FOXO1 gene and type 2 diabetic nephropathy(T2DN). Methods A total of 654 Chinese Han patients with type 2 diabetes mellitus (T2DM;394 without and 260 with T2DN) were enrolled. Six FOXO1 gene tags SNPs were selected using the Hapmap database. The genotypes of six SNPs in FOXO1 were determined by PCR-RFLP, and the clinical characteristics of the subjects were also evaluated. The interaction of SNPs with these clinical factors was analyzed by multiple factor reduction(MDR) method. Results After adjusting for age, gender, DM course, body mass index ( BMI ) , HbA1C , total cholesterol ( TC ) , triglycerides ( TG ) , high-density lipoprotein-cholesterol ( HDL-C ) , low-density lipoprotein-cholesterol ( LDL-C ) , hypertension history, DM family history, smoking, and drinking, FOXO1 rs17446614 variant genotype was significantly associated with an increased risk of T2DN, while rs17446593 variant genotype was associated with a decreased T2DN risk. In the stratified analysis of risk factors, the correlation between rs17446614 and T2DN was unrelated with patient' s gender, hypertension history, and blood TC level. Simultaneously, rs17446614 variant genotype significantly increased the risk of T2DN in people older than 60 years,BMI less than 24 kg/m2 , LDL-C less than or equal to 3. 5 mmol/L , or DM family history. rs2721068 variant genotype significantly decreased the risk of T2DN in people less than 60 years old or without DM family history. rs2951787 variant genotype significantly increased the risk of T2DN in people with DM duration longer than 10 years or with DM family history. A variant genotype rs17592236 significantly increased the risk of T2DN in male or TC higher than 5 mmol/L. A variant genotype rs17446593 significantly decreased the risk of T2DN in male or those DM duration longer than 10 years, or BMI≥24 kg/m2 . The interactions among rs17446614, DM duration, TC, and hypertension history were also observed. Conclusion The genetic variants rs17446614, rs2721068, rs2951787, rs17592236, and rs17446593 in FoxO1 may contribute to the risk of T2DN in T2DM patients.

Compatibility of Radix astragali and Radix salviae miltiorrhiae for the treatment of cardio-cerebrovascular system diseases:research advances / 国际药学研究杂志

Because of the high morbidity and mortality rate,cardio-cerebrovascular diseases,including cerebral embolism, cerebral hemorrhage,cerebral vasospasm and myocardial infarction,have become main diseases threatening human health. Tradition-al chinese medicine(TCM)holds that the basic pathogenesis is Qi imbalances,which could be improved by benefiting Qi and promot-ing blood circulation. The compatibility of Radix astragali and Radix salviae miltiorrhiae are particularly suitable for treating the car-dio-cerebrovascular system diseases by improving Qi deficiency and blood stasis. This paper focuses on the application of Radix astrag-ali,Radix s. miltiorrhiae and their compatibility for treating the cardio-cerebrovascular system diseases. Moreover,our research would offer valuable references for the development of new drugs related to the treatment of cardio-cerebrovascular system diseases.

Neural stem cell transplantation effects on neuronal apoptosis, differentiation and neurobehavior changes in rats with cerebral ischemia / 中国组织工程研究

BACKGROUND:In recent years, neural stem cell transplantation has become a research hotspot in the treatment of brain injuries, such as cerebral ischemia, but the mechanism has not been fully elucidated.OBJECTIVE:To study the effect of neural stem cell transplantation on neuronal apoptosis and differentiation and neurobehaviors in cerebral ischemia rats.METHODS:Ninety Sprague-Dawley rats with cerebral ischemia were randomized into model group, phosphate buffer solution (PBS) group and neural stem cell group (n=30 per group). Another 30 rats were selected as sham operation group with vascular exposure but with no occlusion under anesthesia. Thirty normal 30 rats acted as controls with no treatment. Thereafter, neurological deficit scores, cerebral infarction volume, the number of apoptotic nerve cells,BrdU/NeuN and BrdU/GFAP expression were detected at 3, 7, 14 days after modeling.RESULTS AND CONCLUSION:On the 7th day and 14th day after modeling, the neurological deficit scores, cerebral infarct volume and the number of apoptotic nerve cells in the neural stem cell group were significantly lower than those in the model group and PBS group (P 0.05). On the 3rd day, 7th day and 14th day after modeling, the neurological deficit scores and the number of apoptotic nerve cells in the control group and sham operation group were significantly lower than those in the model group, PBS group and neural stem cell group (P 0.05); on the 7th day and 14th day after modeling, the BrdU/NeuN positive cell count in the neural stem cell group was significantly higher than that in the model group and PBS group (P 0.05). On the 3rd day, 7th day and 14th day after modeling, BrdU/GFAP positive cell count in the neural stem cell group was significantly lower than that in the model group and PBS group (P 0.05). In summary, neural stem cell transplantation for cerebral ischemia contributes to the neuronal differentiation of endogenous neural stem cells in the subventricular zone of the lateral ventricles, reduce neuronal apoptosis, and ease ischemic damage to the rat neurological function.
